The math teacher introduced herself humorously.

Excuse me, are you a teacher? If so, I happen to be a humorous junior two student. In my mind, the teacher's first sentence and self-introduction should not be too formal, so that not many students will have a good impression on you. In our students' impression, the teacher's performance in the first class is often exactly what he felt about the teacher later. So dress funny, whether in clothes or expressions, but don't act too much, so students will think you are mentally ill. . . .

Express more, tell some jokes about mathematics, and don't let the students turn over the books 30 minutes before the first class. Students will find the teacher very boring.

Pretend to be led by the nose when you meet some classmates who like to play tricks on teachers, but don't go too far. Self-mockery in time will bring good classroom effect.

Finally, good luck tomorrow.
